I apologize. I'm not a tech person. So, I'm not familiar with how this software would work. If I have a website, and I put the sign-up form for my mailing list on my website, would that be sufficient? In other words, would the software be able to run using the server of the company that I get web hosting from for my website or could it run off from the server of my internet service provider or do I need to somehow purchase my own, individual server? Thanks!
